Hi Vivek,

no - a bitmap is a bitmap. That what you call "quality" is
that Mathematicas PostScript is resulution independ.
You ma look the graphic on a 72 dpi screen or on a
1200 dpi laser printer output and always the result will
be as best as possible. The bitmap has a fixed resolution and
the only possibility to get a comparable result is to store a
extrem huge bitmap with a hight resolution. You can set the
ImageResolution option to Display[]



to the value you need for printout (600 dpi ? 2400 dpi ?)
and buy a new hard drive to store all your images.

Hope that helps
